问题
I have a two table with the below sample output. tb1 is in time and tb2 is out time
I want to build a query to achieve the below results with null values if row in tb2 not in tb2 or row in tb1 not in tb1:
i need get null if OINDX in table2 and not in table1 or IINDX in table1 and not in table2 and if date not in dates between two date get null row with date only like this photo
this code to create two tables to try code and help me

i use this code to get list dates between two datw
DECLARE @Date1 DATE = '2018-02-07'; DECLARE @Date2 DATE = '2018-02-28';
SELECT DATEADD(DAY,number,@Date1) [Date] FROM master..spt_values
WHERE type = 'P' AND DATEADD(DAY,number,@Date1) <= @Date2

You are looking for left join and gap and islands:
Check it at SQL Fiddle
Query 1:
;WITH e1(n) AS (
select 1 from (values (1),(2),(3),(4),(5),(6),(7),(8),(9),(0)) t(n)
), g as (
SELECT ROW_NUMBER() OVER (ORDER BY n10.n) AS n
FROM
e1 n10
CROSS JOIN e1 n100
CROSS JOIN e1 n1000
CROSS JOIN e1 n10000
),
gd1 as (
select dateadd(day, n, CAST(N'2018-01-01' AS Date) ) as d
from g
),
gd as (
select d
from gd1
where d not in (select [date] from TIMEIN union select [date] from TIMEOUT )
and d between CAST(N'2018-02-07' AS Date) and CAST(N'2018-03-01' AS Date)
)
select TIMEIN.*, TIMEOUT.*, gd.*
from gd
full outer join TIMEOUT on TIMEOUT.[date] = gd.d
full outer join TIMEIN on TIMEOUT.OINDX = TIMEIN.IINDX
order by coalesce( TIMEIN.date, TIMEOUT.date, d)
Results:
| IINDX | USERID | Date | CHECKTIME | CHECKTYPE | OINDX | USERID | Date | CHECKTIME | CHECKTYPE | d |
